The member is fixed to the air-conditioning blowout hole inner surface with a fitting hole and a blowout hole fitting member. A rubbery gasket and a flow straightening gasket are fitted around an outer peripheral part of the member to prevent blown-out air from leaking from a circumference. The member is further provided with an air regulating member provided with a rotary shaft, with which the blown-out air is regulated. There is further provided a mechanism which uses a size-adjustable cooking drop lid for the member, and expands or contracts its circumference to adjust the outer peripheral size.SELECTED DRAWING: Figure 1

Description

The present invention relates to an air regulator that is attached to an air conditioning outlet of an air conditioning system and adjusts the flow rate of blown air.

In recent years, HVAC (Heating, Ventilation, and Air Conditioning) systems and the like have been used in homes, offices, etc. as air conditioning systems. This system circulates blow-out air containing cooling and hot air through ventilation ducts, and adjusts the air volume with valves installed at predetermined locations. By the way, one of the types of air outlet of the system is an anemo type. These are used in the entrances and exits of office buildings, theaters, and shopping malls, as well as in places such as kitchens and subway stations where high temperature and humidity can cause indoor air to become polluted and ceiling surfaces to become dirty. The Anemo type has a structure in which the surface of multiple cone-shaped blades is surrounded by cold blown air, preventing the drawn-in indoor high-temperature, high-humidity air from coming into direct contact with the cone surface, thereby preventing air condensation. There are two types of anemo shapes: round and square, and in both cases, the airflow spreads out radially from the blades and the direction of the airflow is adjusted by moving the cone up and down.

However, there is a problem with the sound of the blown air at the outlet of the air conditioning system. Moreover, if the outlet connected to the ventilation duct is small, the blown air will flow out all at once, creating a lot of noise in a quiet space. Due to the structure, it was difficult to set the air conditioning temperature, and it was difficult to make detailed air conditioning adjustments for each room. Also, the air conditioning temperature settings were adjusted to be a little cool in the summer and not too cold in the winter. Furthermore, since the air volume adjustment damper at the top of the outlet unit is constantly exposed to hot and cold air, the lubricating oil tends to evaporate and the air volume cannot be adjusted smoothly, making it difficult to finely adjust the air volume. For the reasons mentioned above, devices such as wind covers that can be attached to the ceiling or the like and air guides for air conditioning air baffles are on sale to prevent the blown air from directly hitting the body. However, these appliances tend to come off from the ceiling or fixtures if the blowing air pressure is strong. Furthermore, there are problems in that the mounting members are likely to deteriorate due to thermal drying with cold air or hot air, and the external design is also ugly.

The air conditioner of the present invention is used by being inserted into the inner surface of an air conditioning outlet of an air conditioning system. Rubber packing and notch packing are fitted around the outer periphery of the air conditioner to prevent leakage of blown air. The air regulator adjusts the blown air using an air adjusting member provided with a rotating shaft.

The air conditioner of the present invention can be easily attached to an air conditioning outlet of an air conditioning system. Furthermore, the noise of the blown air is reduced, and the equipment is installed inside the system, giving it an excellent external design.

The air regulator is installed in the space below the air volume adjustment damper at the outlet, and is fixed by a mounting part. The shape of the air conditioner is, for example, a disk. Attachment holes for attachment to, for example, an anemo-type air outlet are provided on the outer circumferential portion. A rubber packing is fitted around the outer periphery to prevent leakage of air blown from the air conditioning system. A rotating shaft is provided in the center, and air holes are provided around the rotating shaft through which the blown air passes. An air adjustment member is provided on the rotating shaft, and adjustment holes are provided at positions corresponding to the air holes. The air adjustment member is configured to rotate and adjust the gap between the air hole and the adjustment hole to adjust the blown air. A fixing member is provided at the bottom of the rotating shaft to fix the state of the air hole and adjustment hole after adjustment. An air outlet mounting member having a connecting member such as a chain or string is provided on the rotating shaft portion. At the top or bottom of the air conditioner, a notch packing made of a plastic, breathable material such as cloth or felt and having a disc shape and an upper air hole is provided to prevent air from blowing out from the mounting hole.
Furthermore, the air conditioner of another invention utilizes a conventionally available size-adjustable cooking lid. The outer circumferential size of the drop lid is adjusted by rotating and contracting the circumference in a spiral manner, for example. Here, a screw member is inserted into the center of the drop lid, and the screw member is tightened from below to fix the expanded and contracted outer circumferential diameter so that it does not come off from the blanket 24 of the air conditioning outlet.
